The 8 Ways Urban Demographics are Changing
Cities are what keep the global economic machine humming.
Over 80% of the world’s economic output is derived from activities in cities – and more specifically, it’s estimated that 60% of GDP growth occurs in just the top 600 urban centers.
Given the above, it’s fair to say that the destiny of humankind is directly linked to what happens in major cities. Further, how urbanization plays out over time could end up having a significant ripple effect on the economy, and we should pay close attention to such trends.
Today’s infographic comes to us from Raconteur, and it showcases eight different ways that urban demographics are evolving.
Below we will summarize the changes, along with potential impacts on the economy:
1. A Higher Percentage of Urban Dwellers
Between 1950 and 2018, we went from 30% to 55% of the world’s population living in cities. This has been driven largely by today’s middle and high income economies in places like North America, South America, Europe, and Japan.
The next stage of urbanization will see us move to 68% – more than two-thirds of the world’s population – living in these urban conglomerations. It will be driven by countries in developing markets, creating a potent investing megatrend along the way.
2. The Countries Driving Growth
It’s estimated that three countries will combine for 35% of all urban population growth.
|Rank||Country||Growth in Urban Population (2018-2050)||% of Global Urban Growth|
|World||860 million people||35%|
|#1||India||416 million people||17%|
|#2||China||255 million people||10%|
|#3||Nigeria||189 million people||8%|
In total, there will be 2.5 billion more urban dwellers in 2050 than there are today. Many of these people will experience rising incomes in cities, increasing the global middle class to an unprecedented size.
3. Peaking Rural Populations
On the flipside, it appears the world’s rural population has nearly flatlined, with anticipation that it will peak in absolute terms in the next couple of years. Rural populations have been slowly growing since 1950 until this point.
4. The Rise of Megacities
There will be 43 megacities by the year 2050, which is more than quadruple the amount that existed back in 1950.
The changing geography of the world’s megacities will be one of the major forces that shapes the future of the global economy and accompanying investment trends.
5. New Population Centers
By 2050, more than 70% of the world’s urban population will live in Asia or Africa. Meanwhile, North America and Europe will combine for closer to 15% of that total.
The role of de-urbanization is often downplayed or forgot about when discussing urban demographics, but it is an interesting issue.
Factors such as falling fertility rates, economic contraction, and natural disasters are actually shrinking the size of some cities. In fact, McKinsey predicts that 17% of cities in developed regions will see a drop in population between 2015-2025.
7. Disparities in Urban Growth
The rate for urban population growth is actually trending down across all types of economies – however, these rates come from very different starting points.
High income countries are currently averaging growth of less than 1% per year, and this will continue to decline to below 0.5% per year by 2050. Over the same time period, low income nations will go from 4% to 3% per year.
8. Changes in Average Age
The age distributions in large cities within developed nations will begin to skew older, something we’ve shown previously when looking at the median age of every continent.
The biggest impact here may be felt on dependency ratios in the workforce. With a smaller pipeline of new workforce entrants and a burgeoning population of seniors, this changing ratio is one of the most significant stories impacting urban demographics.
The Hydrogen City: How Hydrogen Can Help to Achieve Zero Emissions
Cities are drivers of growth and prosperity, but also the main contributors of pollution. Can hydrogen fuel the growth of cities with clean power?
In the modern context, cities create somewhat of a paradox.
While cities are the main drivers for improving the lives of people and entire nations, they also tend to be the main contributors of pollution and CO2 emissions.
How can we encourage this growth, while also making city energy use sustainable?
Resolving the Paradox
Today’s infographic comes to us from the Canadian Hydrogen and Fuel Cell Association and it outlines hydrogen technology as a sustainable fuel for keeping urban economic engines running effectively for the future.
The Urban Economic Engine
Today, more than half of the world’s population lives in cities, and according to U.N. estimates, that number will grow to 6.7 billion by 2050 – or about 68% of the global population.
Simultaneously, it is projected that developing economies such as India, Nigeria, Indonesia, Brazil, China, Malaysia, Kenya, Egypt, Turkey, and South Africa will drive global growth.
Development leads to urbanization which leads to increased economic activity:
The difficulty in this will be achieving a balance between growth and sustainability.
Currently, cities consume over two-thirds of the world’s energy and account for more than 70% of global CO2 emissions to produce 80% of global GDP.
Further, it’s projected by the McKinsey Global Institute that the economic output of the 600 largest cities and urban regions globally could grow $30 trillion by the year 2050, comprising for two-thirds of all economic growth.
With this growth will come increased demand for energy and C02 emissions.
The Hydrogen Fueled City
Hydrogen, along with fuel cell technology, may provide a flexible energy solution that could replace the many ways fossils fuels are used today for heat, power, and transportation.
When used, it creates water vapor and oxygen, instead of harmful smog in congested urban areas.
According to the Hydrogen Council, by 2050, hydrogen could each year generate:
- 1,500 TWh of electricity
- 10% of the heat and power required by households
- Power for a fleet of 400 million cars
The infrastructure requirements for hydrogen make it easy to distribute at scale. Meanwhile, for heat and power, low concentrations of hydrogen can be blended into natural gas networks with ease.
Hydrogen can play a role in improving the resilience of renewable energy sources such as wind and solar, by being an energy carrier. By taking surplus electricity to generate hydrogen through electrolysis, energy can be stored for later use.
In short, hydrogen has the potential to provide the clean energy needed to keep cities running and growing while working towards zero emissions.
The 100 Tallest Buildings in New York City
This visualization plots out the tallest buildings in New York City, as well as a few in the pipeline that will change the Big Apple’s skyline forever.
The 100 Tallest Buildings in New York City
If you go to the Big Apple, the city’s signature skyline can make quite an impression.
The fact is, New York City has over 6,000 high-rise buildings in total, 274 of which are skyscrapers standing over 492 ft (150 m) tall. It’s an impressive portfolio of real estate, putting NYC as the number two destination globally for such towers, only behind Hong Kong.
But while some of the buildings have dominated the skyline seemingly forever, it’s also a landscape that is changing fast. New projects coming online will be among the city’s tallest, and they will dramatically alter any view of Midtown of Lower Manhattan for future onlookers.
A List of NYC’s Tallest Buildings
Today’s infographic comes to us from Liberty Cruise, and it shows the tallest buildings in New York City.
Here are the individual profiles of the current top ten:
|Rank||Building Name||Height||Completion Date|
|#1||One World Trade Center||1,776 feet (541 m)||2014|
|#2||432 Park Avenue||1,396 feet (426 m)||2015|
|#3||30 Hudson Yards||1,268 feet (387 m)||2019|
|#4||Empire State Building||1,250 feet (381 m)||1931|
|#5||Bank of America Tower||1,200 feet (366 m)||2009|
|#6||3 World Trade Center||1,079 feet (329 m)||2018|
|#7||53W53||1,050 feet (320 m)||2018|
|#8||Chrysler Building||1,046 feet (319 m)||1930|
|#9||The New York Times Building||1,046 feet (319 m)||2007|
|#10||35 Hudson Yards||1,009 feet (308 m)||2018|
Two of the biggest skyscrapers, the Chrysler Building and the Empire State Building, were erected during the Great Depression and still crack the top ten list today.
The Chrysler Building was actually the first skyscraper ever to be built at a height exceeding 1,000 feet. Meanwhile, the Empire State building, which was finished one year later, was the “world’s tallest building” for nearly 40 years.
However, as you can see, the rest of the buildings on the top ten list are more recent builds. It’s a testament to how fast the skyline of New York City has changed even in the last decade.
Towers in the Pipeline
But that’s not all, because the skyscraper boom in NYC hasn’t ended yet. The following megatowers are closing in on completion, and will displace many at the top of the current list:
111 West 57th Street
This building is set to be operational in mid-2019, and it’s already very noticeable on the NYC skyline. With a height of 1,428 feet (435 m), it will be the “skinniest” skyscraper in the world when completed, with a width-to-height ratio of 1:23.
Central Park Tower
This building, which was designed by the same people who did the Burj Khalifa in Dubai, will be the tallest building in the country by roof-height when done in 2020. It will clock in at 1,550 feet (472 m), making it the most sky-high residential building in the world.
45 Broad Street
With a height of 1,200 feet (366 m), this new building in Lower Manhattan is expected to be completed by 2021. If it were finished today, it would tie the Bank of America Tower for the fifth spot on a list of tallest buildings in the city.
This massive building will be the fourth tallest in the city when completed in 2021. Standing at 1,401 feet (427 m), it will have a highly anticipated observation deck set 1,000 feet above the ground.
